This class will have midterm on Nov. 3. For more details, please contact Zhao Laoshi at yz32@yahoo.com

In today’s class, I guided students to work on factorization of algebraic expressions, especially the special expression factorization, such as a^2+2ab+b^2, a^2-b^2, etc. In the quadratic expression factorization, students learned the definition of quadratic expression and the standard form, special … Continue reading →

Today, students continued to work on Algebra 1, the linear equations. Students understand what the linear expressions, linear equations are. The solutions to one-variable linear equations are one solution, no solution and infinite solutions. In addition, students learned the procedure … Continue reading →

In today’s class, students studied expansions of Algebraic expression, especially the method of handling “sign” in algebraic expressions. A few special products were introduced that are so important in the quadratic expression section. By using those special products, we are … Continue reading →

In the new content section, students learned algebraic fractions, simplification of algebraic fractions, addition, subtraction. The key to implement simplification is factoring the expressions of numerator and denominator correctly, and cancellation can be only done in the form of factors; … Continue reading →

In the new section of the course, I reviewed the scientific notation and introduced the operation of numbers in the form of scientific notations. Students also studied the significant digit and applications. Here is the homework for the contents above … Continue reading →

Today, students continued to work on exponent computation and simplification, especially with fractional exponents. Simply speaking, all laws of exponents that were introduced to students last week are also valid for the fractional exponent. Most importantly, the relation of radical … Continue reading →

Today, students continued to study laws of exponents with fraction exponents. All laws of exponents introduced for the case of integer exponents are also valid for fractional exponents. Additionally, radical numbers and the relation with fractional exponents were described and … Continue reading →

In the first class, we reviewed the basics, including number tree, order of operation, commutative, associative, distributive property, and factoring, equation, exponent. The exponent is very important knowledge and will be used in Algebra studying. In exponent section, we started … Continue reading →

In the first class, students worked on exponent and related computation/simplification. Today’s class is shorter because of the distribution of workbooks. The integer exponent was the first topic that students started with. During the introduction of exponent laws, students learned … Continue reading →
